Title: Improvements in or relating to embossing presses
IPC: B41F19/06
Filed: 1933-05-05
Abstract: 412,025. Embossing &c. presses. CLIFTON, E., CLIFTON & CO., Ltd., W. J., 11, Plough Court, Fetter Lane, London, and RAMSDEN, C., 159, Old Church Road, Romford, Essex. May 5, 1933, No. 13151. [Class 100 (i).] Sheet-registering devices.-A hand-operated lever embossing or like press is provided with a curved or a backwardly extending paperguide mounted or formed adjacent the dies and combined with an abutment or stop which determines the amount of margin between the edge of the paper and the embossment. In the form shown in Fig. 5, a double-walled paper-guide b, the entry to which is on a level with the space between the dies c, d, is disposed on the base a of the press, the upper surface of the guide being corrugated as at f so as to provide a number of grooved passages in any of which a pin or rod g can be positioned to act as a stop for the paper inserted between the dies. A second pin j adapted to extend through an additional slot k formed above the guide b is provided with a downwardly extending arm l which constitutes a side stop for the paper, and the slot k is formed with apertures which can be engaged by a projection on the pin j whereby the latter may be temporarily positioned. The pin is preferably provided with a parallel extension which passes beneath the guide b. If desired the pin g may be provided with a forward extension which can be positioned at varying distances from the side edge of the paper guide b, and thus eliminate the use of the second pin j. In a modification a double-walled paper-guide of spiral form is employed, the double walls being united at their inner ends, and an adjustable stop engaging frictionally over one or both walls can be moved around the guide to limit the movement of the paper thrust therein. This arrangement enables documents to be embossed where the margin is greater than the gap of the press would normally permit. In another form, shown in Fig. 7, the paper follows the curvature of the arm of the press and is stopped by fingers n disposed one at each side of the press. The fingers have slots engaged by screws p, and can be adjusted in various positions. The forward ends of the fingers may be hooked. These fingers may be used in conjunction with the above-described spiral paper-guide. In a further modification a single guide-plate extends backwardly from the dies, and is provided with a frictionallyengaging adjustable stop. Side stops may be used with all the different constructions, and they may take the form of a slide which can be withdrawn by varying amounts from the base a of the press, or may be constituted by separate adjustable spring members. All the constructions may be provided with an inclined member such as t, Fig. 5, to facilitate the insertion of a sheet of paper between the dies.

Title: An improved metal rolling machine applicable for the manufacture of electric conductors
IPC: B21B15/02
Filed: 1936-05-09
Abstract: 476,485. Rolling electric conductors. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., HUNTER, P. V., and HILL, H. May 9, 1936, No. 13169. [Classes 83 (ii) and 83 (iv)] Twisting.-In a method of making a pre-spiralled shaped solid conductor, particularly a sector-shaped rod 1, Fig. 7, for forming part of a three-core cable, from a rod of circular or other cross-section, the rod is passed between one or more sets of rolls 3 which form a pass 4 of the shape to be given to the rod and which rotate on their axes and also revolve body round the axis of the work. The rod is driven from a reel 2 and if it is of hexagonal shape it may pass through a corresponding guide 5 which resists twisting of the rod. The rod may be rolled for either hot or cold and for hot-rolling the reel may be housed in a furnace 6. In the case of copper rods, the rod may be annealed after passing the rolls 3 by a cooling tube 7 through which water is circulated. A second rolling operation may be performed by rolls 8 having a pass of the required final shape and arranged at an adjustable angle to the first pass to allow for the rotation of the first pass while the rod moves between the passes. The rod may finally pass to a reel 10 driven through a slipping coupling. The rolling mill, Fig. 4, has the rolls 3 mounted in a frame comprising spaced side walls 11 and hollow trunnions 12, 13 which can rotate in bearings 15, 16 to impart the orbital movement to the rolls. The frame is driven from a shaft 20 through gears 19, 21, 22. As the frame rotates, a fixed bevel gear 35 is engaged by a pair of bevel gears connected through gears 38 to gears on the roll shafts to rotate the rolls on their axes. The lower roll is fixedly mounted in a member 25 secured by a cap 27, but the upper roll is adjustable tangentially to its driving gear 38 so that adjustment does not disengage the gearing. Other forms of driving gearing may be used. Where two passes are used as shown in Fig. 1, the two roll stands may be mounted on a common bed plate and be driven from a common shaft. The second set of rolls are preferably axially rotated at a higher speed than the first set through a slipping coupling to avoid buckling of the work. A detachable coupling in the common driving shaft allows relative angular adjustment of the passes. In a modification, three rolls may be used in each set.

Title: Improvements in or relating to telephone signalling systems
Inventor: LEMAN HUGH SPENCE
IPC: H04M19/04
Filed: 1955-05-06
Abstract: 793,543. Substation circuits. STANDARD TELEPHONES & CABLES, Ltd. May 6, 1955, No. 13188/55. Class 40 (4). [Also in Group XL (c)] A substation circuit comprises a transistor oscillator arranged to oscillate when an incoming calling signal is received, the oscillations being fed to an electro acoustic transducer which normally serves as the transmitter of the subset. This arrangement ensures that the subscriber will not receive the calling signal in his ear and also permits the use of amplitude limiters connected across the receiver as " click suppressors." In the embodiment of Fig. 3 the transistor used in the oscillator is also used as part of the amplifier for outgoing speech signals. Thus the tuned circuit for the oscillator W1 comprises the inductance of the transmitter TX and the capacitor C<SP>1</SP>. In the idle condition a switch-hook contact S1c connects up a positive feedback circuit over condenser C2. Incoming ringing current, received over condenser C3, provides intermittent biasing current for the transistor which thus produces an audio frequency modulated at ringing current frequency and this causes the transducer TX to emit a corresponding calling signal. When the subscriber operates his switch-hook contacts S1, the feedback condenser C2 is disconnected and the transistor W1 operates as the first stage of an amplifier for speech falling on the transmitter TX, the second stage of the amplifier being connected to line via an anti-side-tone circuit AST. Condenser C3 is short-circuited to provide a D.C. loop to the exchanger, from which biasing currents for the transistor are obtained. The usual dial contacts may be provided. A second embodiment, Fig. 4, uses a local battery, but is capable of adaptation by adjustment of link LK either for working to a central battery exchange or on a local battery point-to-point basis. In this case an inductance coil LC is provided in the tuned circuit of the oscillator W1, the transmitter TX being transformer coupled to the collector of the transistor. With the hook switch or pressel switch S3 unoperated the oscillator W1 is arranged to be energized either by ringing current (central battery working) or incoming D.C. (point-to-point working). Outgoing speech is amplified by the two-stage transistor amplifier W2, W3. In either case the local battery B is used to energize the transistor amplifier. For outgoing signalling in point-topoint working the switch S2 is thrown to connect the battery B to line for energizing the distant transistor oscillator. The tone signal derived over the series resistance R4 is heard in the receiver RX as a " ring-back " tone.

Title: Improvements in or relating to a coin testing device
Filed: 1958-04-28
Abstract: 831,589. Coin-freed apparatus. PATZER, W. April 28, 1958, No. 13462/58. Class 27 A coin-testing device comprises a vertical slot 14 formed between plates 15, 16, a laterally inclined slot 20 formed in the plate 16, and a pivoted plate 25 normally urged into a position in which its inclined upper face 29 projects through the slot 20 to form an obstruction preventing an incorrect coin from falling through the slot 14 but causes it to roll sideways therefrom to a rejection shoot. The plate 25 is held in this blocking position by a latch comprising a bell-crank 36 having a downwardly extending arm 37 which latches the end 28 of the plate 25. The plate swings clear of the slot 14 under the weight of a correct coin which is also tested for diameter by the plate-latching means as it falls towards the inclined face 29 of the plate 25, the coin being checked between a fixed abutment 34 and a pin 33 on the bell-crank 36. When in the plate-latching position, the distance between the gauging points 33, 34 is slightly less than the diameter of a correct coin, the weight of which is sufficient to move the pin 33 against the influence of a counterweight 35, thereby moving the end 37 of the downward arm of the bell-crank out of contact with the end 28 of the plate 25 in which a detent is formed to allow the plate to pivot clear of the latching means under the weight of the coin on its inclined face and thus to pass the coin into the operative part of the apparatus. Coins of incorrect diameter or weight are thus obstructed by the plate 25 and roll laterally to the rejection shoot. The device is particularly applicable to the apparatus described in Specification 810,031 for receiving coins in a shoot 10 and separating them into various denominations having indexed runways 11, 12 in which the rate of travel of the separate coin is controlled by permanent magnets 13, 18.

Abstract: 751.280. Windscreen cleaners. FORD MOTOR CO. Ltd. May 10. 1954 [May 29, 1953], No. 13579/54. Class 138(1) In a windshield wiper a main supporting yoke 47, Fig. 4, for a wiper blade 44 is pivotally connected at spaced points (48, 49) to the respective outer ends of a primary arm 29, mounted upon and driven by a rotatable pivot shaft 23, and a secondary arm 37 adapted to be moved lengthwise relatively to the arm 29 by angular movement of the arms in a plane containing the axis of the shaft 23. As shown in Fig. 3, the inner ends of the channel-section arms 29, 37 are pivoted, respectively at 32, 38, on a head 27, secured at 26 to the shaft 23, the arm 37 telescoping into the arm 29. The pivots 32, 38 are at right-angles to the shaft 23 and the arm 29 is spring-urged towards the curved windshield surface. At their outer ends the arms 29, 37, Fig. 4, have offset integral flanges 41 and 43 pivotally connected to pins 48, 49, parallel to the shaft 23 and carried by the yoke 47 which supports two secondary yokes 46, connected to the blade 44. When oscillated across the windshield the arms are also moved towards or away from the windshield about the pivots 32, 38, this movement causing the outer end of the arm 37 to move lengthwise relatively to and within the arm 29 to move the pivot pin 49 angularly with respect to the pin 48 and thereby alter the inclination of the . blade 44 with respect to the arms 29, 37. The blade is thus retained in a generally vertical position on the side portions of the windshield which are of the greatest curvature and bending or flexing of the blade in these areas is reduced. Moreover the lower extremity ' of the blade is advanced closer to the side edge of the windshield to increase the area wiped.

Abstract: 150,408. Westinghouse Brake Co., (Westinghouse Air Brake Co.). May 29, 1919. Sand, salt, and the like, distributing on wheel tracks.-The supply of air from the main reservoir 2 of a fluid-pressure brake system to an additional reservoir 3 which operates devices auxiliary to the brake system, is automatically controlled by governor devices acting by differential pressures in such a way that while in lap, service, and emergency positions of the driver's valve fluid is supplied to prevent depletion of the additional reservoir at such times, in the release and running positions air is fed only when the main reservoir pressure is greater than a predetermined amount. The governor device 1 permits supply to the additional reservoir 3 through a valve 5 during running and release of the brakes, so long as the main reservoir pressure is sufficient to overcome the pressure of an adjustable spring 12 and the pressure in the feed valve, pipe 13. During lap, service, and emergency applications of the brakes, the feed valve pipe contains air at main reservoir pressure which, with a spring 17, causes a piston 16 of a second governor device 4 to open a valve 18 through which air is fed to the additional reservoir.
